Default Scratch Built Ignition???

I agree the number of times the ignition fires per minute is the same no matter what the diameter. However, if you're talking about dwell time, the time the coil stays charged, is dependant on the size of the magnet and the diameter of the hub. The bigger the diameter the faster the pick-up crosses the magnet, hence the dwell time is shorter.
